Byte access type in page mode
The NRD and NCS signals are held low during all read transfers, whatever the programmed val-
ues of the setup and hold timings in the User Interface may be. Moreover, the NRD and NCS
timings are identical. The pulse length of the first access to the page is defined with the
PULSE.NCSRDPULSE field value. The pulse length of subsequent accesses within the page
are defined using the PULSE.NRDPULSE field value.
In page mode, the programming of the read timings is described in
Table 15-7.
The SMC does not check the coherency of timings. It will always apply the NCSRDPULSE tim-
ings as page access timing (t
programmed value for t
The byte access type configuration remains active in page mode. For 16-bit or 32-bit page mode
devices that require byte selection signals, configure the MODE.BAT bit to zero (byte select
access type).
